SOURCE: Blower won't shut off

You will need a Blower motor resistor and maybe a blower motor resistor connector end. If you look under the dash on the passenger side(may need to remove smooth black cover, vents will be sticking out) you will see a connector going straight up into the blower motor resistor(7 wires/slightly in front of blower motor). Pull out the connector and check for melted terminals/wires. If no melted terminals just replace blower motor resistor with part # 89019088 per GM to revert to part before 04 in order to stop blower motor resistor relay from hanging. Let me know if i can help more.

SOURCE: 1992 cadillac deville - hvac blower motor does not shut off.

replace the relay , when a relay sticks like that , a good test is to slap it with something like the handle of a screw driver , see if it un-sticks , its not a fix , just a test . cheers'

SOURCE: 92 buick century power antenna motor wont shut off

Well, even if you pull the connector (under carpet) apart with gray white and green wires(ones seen going to motor from door gap when opened) it still doesn't stop. next access point is from behind mud gaurd in wheel well. If I can't disconnect it from there I will just cut the bloody wires.

GMC 2004 Envoy blows heat even with blower off ... Why ?


The relay in your blower motor is stuck on, there is a TSB for this issue. Replace the blower motor resistor and you'll be back in business.
How does the resistor get power if the fuse is pulled?
Replacing the resistor will cure both problems. TSB is a technical service bullitin seen below

My blower does not shut off when I cut my car off. I have to pull the fuse under the hood to make it shut off. When it's on, it runs on high and I can change it or the tempature controll.


If you vehicle has the automatic temperature control system, where you can set the desired temperature using the digital temperature readout, then you most likely have a failing blower motor speed control module. This is an electronic module the controls the blower on/off and speed operations and when it fails it often won't shut off the blower when you shut off the vehicle which can result in a dead battery if you don't pull the power supply fuse. Its a small rectangular box located under the right side of the dash [passenger side] by the blower motor and isn't to hard to change. Hope this helps and good luck!

you have a short to power which will cause it to stay on constantly check your blower motor resistor pack to ensure that it is working and check the wires going to the blower to make sure you have a power and a ground
